NOTE
To reduce clutter, Coincident constraints display by default as small, light-blue
squares. You can use an option in the Constraint Settings dialog box to turn
them off if necessary.
Modify Objects with Geometric Constraints Ap-
plied
You can edit constrained geometric objects with grips, editing commands, or
by relaxing or applying geometric constraints.
By definition, geometric constraints that are applied to geometric objects limit
the editing actions that you perform on the objects.
Modify Constrained Objects with Grips
You can modify constrained geometry using grip editing modes. The geometry
will maintain all applied constraints.
For example, if a line object is constrained to remain tangent to a circle, you
can rotate the line and change its length and endpoints, but the line or its
extension will remain tangent to the circle.
If the circle was an arc instead, the line or its extension would remain tangent
to the arc or its extension.
